What is the process before spraying aluminum veneer

Before spraying aluminum veneer, what is the specific spraying process? As a manufacturer of aluminum veneer in Weifang, let me take you to understand the process before spraying aluminum veneer!

It is to rinse with cold water from the faucet to remove all polishing aluminum dust on the aluminum veneer substrate.

Clean the aluminum veneer substrate again with alkaline water. Alkaline substances can effectively dissolve various oils and fats on the aluminum veneer substrate, and replenish the stains that cannot be removed by clean water. Use the faucet to rinse away any remaining alkaline substances with cold water, preparing for the next step of the process. The purpose of using acidic solution to clean the substrate of aluminum veneer products again is to remove the residues on the surface of the aluminum veneer substrate that have undergone chemical reactions with the acidic solution. Clean the aluminum veneer substrate again with clean water. Chromate the aluminum veneer substrate. Clean the chrome plated curved aluminum veneer substrate with clean water. The punching shape of aluminum veneer is an important parameter that determines the appearance of the product. Generally speaking, punching aluminum veneer can be designed in circular, square, plum blossom shaped and other shapes according to actual needs. The larger the mesh, the lighter the weight of the aluminum veneer, but the weaker its resistance to pressure and tension, which affects the application of punched aluminum veneer. So customers need to design the size of the mesh according to their actual requirements and the needs of the project.

The punching rate of aluminum veneer determines the density of patterns on the aluminum veneer. Overly dense punching can lead to a decrease in the pressure resistance of the aluminum veneer and is not conducive to processing, while punching too wide is not aesthetically pleasing and lacks artistic sense. Therefore, punching on perforated aluminum veneer must be uniform in order to meet the requirements of engineering design.
